PAPER-BAG ,MACHIN E.

SPECIFICATION forming part of Letters Patent No. 251,402, dated December 27, 1881.

Application filed August 12, 1881. (No model.)

To all whom it may concern:

Be it known that I, ANTHONY BEYER, of Oakland, county of Alameda, State of Callfornia,have invented new and useful Improvements in Paper-Bag Machines and I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to certain improvements in that class of machines used for makin g paper bags; andit consists in an improved construction of the forming and folding plates, and in the addition and application to the ordinary general operation of folding the paper into bags of a novel means for pasting the bags, and also for printing any desired design orlabel thereon. v

It further consists in the mechanism where- I by the device is operated, all of which will be fully seen in the following particular descrip-. tion and by reference to the accompanying drawings.

Figure 1 is a perspective view. Fig. 2 is a longitudinal vertical section. Fig. 3 is a transverse vertical section. Fig. 4 is a detail of construction.

Let A represent a table. Hinged to its rear edge on top is a plate,B, which I call the forming-plate. This lies transversely upon the table, and is adapted to have a vertical swing about its hinge. This is accomplished by means of the connecting-rod O, which is attached to the rear part of the plate B and extends down through the table. Its lower end is attached to the treadle D, which said treadle is hinged to the frame, as shown. When the treadle is pressed down it draws the plate B down flat upon the table, and when the footis taken from it a spring, a, weight 0, and cord b return it to its place.

Upon the table A, on each side of the forming-plate B, are the folding-plates E and F, respectively. Thesehaveguidesmontheirlower surfaces, which fit in slots in the table, and they are thus adapted to slide toward each other or recede, one of them, F, being made to start first and the other, E, to move as soon as F has started. The guides m rest upon rollers n, journaled under the table, and are thus enabled to slide easily as well as being supported. They approach each other, but-do not touch. Both folding-plates pass above the forming-plate B. This movement is upon the ordinary principle of paper-bag machines of this class. I accomplish the movementof these plates as followsi Under the table is an upright lever, G, pivoted to a cross-piece, I. Its lower end passes down to the treadle and past a roller, d, in its side. It is bent outwardly, as shown, so that when the treadle is pressed down it forces the lever over and throws its upper end toward the right hand of the table, as shownin Fig. 1. Under the top of the table, upon a suitable piece or support, isjournaled a roller, 6. The end of the lever G extends up to this roller, as shown in Fig. 2, and has acord, f, attached to its top. The cord passes over the roller 0, and is attached to one of the guides of the folding-plate F. Attached to the other end of the guide is a cord, g, which passes over a pulley, 7i, and back to a spring, i, which is securedunderthetable. Now,when thetreadle is pressed down it forces the lever G over. This draws on the cord f and causes the plate F to slide to the center. When the pressure is removed the spring 2' causes it to return.

Upon the other side of the treadle is the lever E. This leverresembles lever G; but its bent portion, at the bottom, is lower down, so that it is not acted upon by the treadle until pushed farther down, and until lever G has been acted upon. Above is a small roller, is. The top of the lever Hextends to it, and has a cord, l, at tached to its top. In the end of the central guide of the folding-plate E is pivoted a bellcrank lever, I, one arm of which extends through the table and lies nearly horizontal above, and the other is below the table, remainin g vertical. The cord Zis attached to the end of the vertical arm of the lever I. A cord, m, is attached to the same arm a little above, and passes to a pulley, a, and thence down to a spring, 0, attached to a piece under the table. When the treadle is pressed down the lever H is thrown back and the cord l pulled. This causes the bell-crank lever I to be so moved that the arm above is pressed down; but at the same time the folding-plate E is drawn over to the center to approach the plate F, before described. The spring 0 and cord m return the plate E when the pressure is removed.

J represents the paster. It consists of a trough, as shown, below which is jonrnaled a pasting-roller pad,j. The bottom ofthe trough has an aperture its entire length, so that the pasting material which is put in the trough passes through upon the pad j. The trough has a shank, p, which is journaled upon a shaft, q, attached to the table, as shown. Upon the same shaft-is an arm, 1, which extends forward under the horizontal arm of the bellcrank lever I. When this arm of the lever I is depressed, as heretofore described, it presses down the arm r and causes the pasting-pad-j to descend and come in contact with the paper below, as hereinafterexplained. Araised ridge, K, upon the plate E holds the end of the paper up to receive the pasting-pad.

L represents the device for folding over the bottom of the bag upon the sides after they have been folded by the plates E and F. It consists of a plate having an inclined front, behind which is a roller, 8. This plate is adapted to slide forward upon the table, and,like the folding-plates, it has guides, which pass down through slots in the table.

Upon the rear end of the central guide is a bell-crank lever similar to the lever 1, and under its upper arm is the arm of the paster, and the paster itself is attached, as shown, exactly similar to the paster J,just described, and operates in the same way to paste the bottom of the bag. This is shown in Fig. 4. 1

The means of moving the plate L, I will now describe.

Attached to the forward end of the trcadle is a strap, M, the upper end of which winds upon a drum, N,journaled under the top of,

the tablejust about below where the plate L is. This drum has attached to it a cord, t, the other end of which is attached to the end of the bell-crank lever mentioned in a similar manner to the cord Z, before described. Another cord, to, is attached to the same lever, and is also attached to a shaft, 0, which has a cord, 1), wound upon it, the other end of which is attached to a spring, w. The strap M is of such a length that it will not be drawn tight by the trcadle until it has gone down some distance and until it has operated the foldingplatcs. WVhen it does tighten the strap it revolves the drum N, which Winds up the cord t, so that the plate L is drawn forward, and at the same moment the paster is operated in the manner already shown. When the pressure is removed the springs 20, acting through the cords '0 and a and shaft 0, return the plate L. The paper is previously cut out in the ordinary manner for bags. It is laid upon the table in properposition. The treadleIis up and the forming-plate also. The sides of the paper rest upon the folding-plates and the end upon the plate L. Now the trcadle is pressed down. The rod 0 draws down the forming-plate B immediately upon the centerof the flank. The lever G is then acted upon and draws the folding-plate F over, folding its side of the paper over upon the top of the forming-plate. The lever H is next acted upon, and as the tension is brought upon the cord 1 the paster J descends and deposits paste upon the edge of the paper, which is then folded over upon the other side by the sliding plate E and pressed down. The strap M is then drawn tight, and the end plate, L, slides forward, its paster acting at once, and the end of the paperisfolded over and rolled down by the roller 3 of the plate. When the pressure upon the treadleis removed its spring and weight return it, and the various springs herein described return the plates and leave the bag formed upon the plate B. It may then be drawn oft.

I have further a printing attachment, which performs its work during the operation just described, and which I will now explain In the top of the table A, under the formingplate B, is a hole, P, just about where thecenter of the bag comes. Beneath this hole, and secured to the under side of the table, is a ver tical frame, Q, having suitable guides, as shown. In this frame is the printing stamp or form R, containing any device or words found desirable for advertising, &c. The printing-form has secured underneath vertical rods S, which pass down through the guides of the frame Q. The stamp or form R is directly under the hole P, and is adapted to be raised up through it to touch the bag above. This is accomplished as follows:

Attached to the front of the table is a springrod, T, the other end of which extends toward the central guide-rod, S, of the stamp, and is connected therewith by a short cord, m. A cord, 3 is attached to the spring-rod T, and also to the drum N. Now, the pressure upon the trcadle and tension upon the strap M, which turns the drum N, wind up the cord 3 and raise the spring-rod T. This raises the stamp or printing-press R and prints the bag. when the pressure ceases the spring rod returns the stamp.

In order to keep the stamp supplied withink, I have the following: Passing under the table transversely and lyingupon appropriate guiderollers is a strip, U. One end of this extends toward the stamp, and is provided with an inkroller, V. This is adapted to move back and forth over the stamp by the means now explained.

Bigidly attached to the rear of the trcadle is a rod, W, which stands at about right angles with the trcadle and extends upward to the table. Its end is connected with a cord, 2, which passes over a pulley, a, and is then connected with the end of the strip U. Connected with the end of the strip U, also, is another cord,

1), which is conducted forward over a pulley, X, and has upon its end a weight, Y. When the trcadle is in its normal position-that is, raisedthe cords described are long enough to permit the ink-roller V to remain at the forward side of the press but when the trcadle is pressed down the rod W is thrown forward. Thispulls the cord 2 and draws the strip U and ink-roller back, thus causing theink-roller to pass over the type and get out of the way before the stamp rises. When the treadle is allowed to rise the weight Y and cord I) pull the strip U and ink-roller forward again over the stamp.

I have a further improvement, the object of which is to save time in counting the bags after they have been made.

Attached to the table in a convenient position for the purpose is a ratchet-wheel, Z, containing a number of teeth-say, for example, fifty.

A is a pawl attached to the rear end of the treadle. It has a hook upon its head which is adapted to engage with the ratchet-wheel Z, and every time the treadle is pressed down the pawl pulls the said wheel around one tooth. Upon the face of the ratchet-wheel is a small pin or lug, e.

Pivoted to a cross-piece, as shown, is a bellcrank lever, B, one arm of which extends over by the side of the wheel and the other extends upward to the side of a gong, C. When the treadle has been pressed down fifty times the ratchet-wheel will have revolved, and its pin 6 will raise the arm of the bell-crank lever B, and when it slips past said lever will fall back and cause the gong to sound. I will then know I have made fifty bags.

If I want to make more than one size of bags, I change the forming-plate B for a larger or smaller one, and by any suitable means ad- 'just the paster J to the changed size. This can be done, for instance, by making the shank p of the paster extensible in any manner.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
